S. Blessing P. Grannis February 16, 1995 D0 Conventions for Writing PRL/PRD Papers, Version 1.1 ------------------------------------------------------ 0. Macro There is a file with TeX definitions in D0$D0TEX:D0_STYLE.TEX which follow these rules. EXAMPLE_TABLE.TEX will produce a table showing the defined symbols and their output. Include the line "\input D0$D0TEX:D0_STYLE.TEX" in your .TEX file. Soon there will be a command file to run which will replace the symbols with their definitions in your .TEX file (necessary for submission to PRL/PRD). Or, you can just use the definitions presented directly. 1. Particle names a. Intermediate vector bosons should be called "$W$ boson(s)" and "$Z$ boson(s)." Never use $W$'s or $W$s. b. The $Z$ in "$Z$ boson" or in a reaction should not have a superscript of 0. c. Other particle names should be spelled out: "muon(s)," "electron(s)," etc. when used in a sentence. d. $W$ without the word boson attached may be used as "$W$ pair production" and in similar phrases. e. "Top quark" should be used instead of "top" in most places (i.e. "top quark mass" instead of "top mass"). f. Top quark and bottom quark may be shortened to "$t$-quark" and "$b$-quark." g. The neutrino symbol, $\nu$, should not have any subscripts. h. J/Psi should use a lower case psi: $J/\psi$. 2. Symbols a. All symbols should be slanted (i.e. in math mode). b. Momentum is a lower case $p$. Transverse momentum is a lower case $p$ with an upper case $T$ subscript: $p_T$. c. Energy is an upper case $E$. Transverse energy is an upper case $E$ followed by an upper case $T$ subscript: $E_T$. d. When a subscript is more than two related letters, use roman type. If i,j,k are separate subscripts, $A_{ijk}$ with i,j,k all slanted is correct. If the subscript is an abbreviation using two or more letters, they should be roman: $A_{\rm EM}$. (If you are using REVTeX, use \test rather than \rm when in math mode - the results are a little better.) e. The number of expected events should be written as "$N_{\rm pred}$" and not as "$N_{\rm exp}$" (since "exp" could mean experimental or expected). f. Use \cal in math mode for symbols like L (luminosity), I (isolation), A (aplanarity), R (distance in eta-phi space), etc. g. Use $\cal{R}$ with subscripts for the position difference in eta-phi for two final state particles. Use $\Delta\cal{R}$ with a subscript for the position of a final state particle relative to a jet cone axis. h. Trigonometric functions should be in roman type. Natural logarithm should be "ln" and log base 10 is "log"; both are in roman script. When in math mode, use \ln, \sin, \log_{10} (the base should be specified), etc. i. Use an upper case "M" for the mass of the W boson, Z boson, and Higgs. Use a lower case "m" for other particle masses. 3. Units a. All units should be written in roman script. b. All masses should be in "GeV/c$^2$." c. Momentum should be in "GeV/c." d. Add the word "events" as units when quoting the number of events (i.e. "the resulting background is 4.0 +/- 1.3 events"). 4. Word combinations a. "Monte Carlo" is two words, both capitalized. b. "Pseudorapidity" is one word, no hypen, capitalized only at the beginning of a sentence. c. "Cross section" is two words, capitalized only at the beginning of a sentence. 5. D\O a. Our experiment should always be written with a slash thru the zero, "D\O" (note that the "zero" is actually an upper case "O"). b. Names and words like D\OGEANT, etc. which include D\O have the slash. Note that "D\O GEANT" should produce no space between "D\O" and "GEANT," as you want. c. D\O Notes should use an upper case N. 6. Figures a. At the beginning of a sentence, use the word "Figure." Within a sentence use "Fig." and not "fig.," "Fig," etc. b. When there is an "a" and a "b" figure, they should be referred to as "Fig. 9(a)," and "(a)" and "(b)" should be used in the caption and in the figure. 7. Punctuation a. Dates should be given as "April 1961" rather than "April, 1961." b. The dash, when used as an article of punctuation (e.g. "the measurement sucks --- we messed it up"), should use the triple hyphen in ordinary (not math) mode. Use a double hyphen to indicate a range: "5--10." c. Plurals of acronyms should have an apostrophe (e.g. "PDT's"). d. Quotation marks are placed after commas and periods, before colons and semi-colons. e. New or special usage calls for quotation marks around the word or phrase (e.g. "non-Standard Model, ``anomalous,'' couplings"). Do not use quotation marks around standard nomenclature. f. Always use the special left quote characters `` to open quotes and right quote characters '' (not the double quote ") to close quotes. Use double quotes, ``droopy drawers,'' in preference to single quotes. g. The plural of something belonging to two people should have "'s" after the last person's name (e.g. "Grannis and Blessing's style guide") h. Be consistent in the use of a comma before "and" or "or" in a series of three or more. APS prefers the comma to be present. 8. Miscellaneous a. Spell out whole numbers when the number is less than or equal to ten (i.e. "four jets" instead of "4 jets") or when the number is at the beginning of a sentence. Exceptions are when there is a list of numbers, some larger than ten, when the number is used as a noun, and when the number is a measurement followed by a unit. b. Program names should be written in upper case letters, preferrably of smaller point size than the text: "We used {\smaller ISAJET} to ...." c. Use "pdf" instead of "PDF" as an abbreviation for "parton distribution functions." d. Use American spellings of words. e. Drafts of papers should have "DRAFT" printed on them to make them obvious. To do this, include "\d0draft" after "\begin{document}." f. Use the roman font for "e.g." and "i.e."
